SAMUEL BRONSTIEN, OF ST. PAUL, MINNESOTA.

WIRE FABRIC.

To all whom it may concern Be it known that I, SAMUEL BRonsrmN, acitizen of the United States, residlng at St. Paul, in the county ofRamsey and State of Minnesota, have invented certain new and usefulImprovements in Wire Fabrics, of which the following is a specification,reference being had to the accompanying drawings.

T his invention relates to certam improvements in wire fabrics and hasrelation more particularly to that class of fabrics employed for bottomsof beds, couches and the like; and an object of the invention 1s toprovide a device of this general character of a novel and improvedconstruction and wherein are employed a plurality of wire units or linksof duplicate fo rmation.

It is also an object of the invention to provide a bedfabric of thisgeneral character of a novel and improved arrangement possessingpronounced flexibility and so arranged that the weight imposed upon apart thereof does not affect the remainderof the fabric.

Furthermore, it is an object of the invention to provide a fabric ofthis general character of a novel and improved arrangement which issubstantially noiseless.

The invention also consists in the details of construction and in thecombination and arrangement of the several parts of my improved wirefabric whereby certain important advantages are attained and the deviceis rendered simpler, less expensive and otherwise more convenient andadvantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in theappended claim.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a fragmentary view in top plan of a fabricconstructed in accordance with an embodiment of my invention, and shownin applied position; Fig. 2 is an enlarged sectional view takensubstantially on the line 22 of Fig. 1; Fig. 3 is an enlarged sectionalview taken substantially on the line 83 of Fig. 1; Fig. 4 is afragmentary view in perspective, illustrating the interlockingengagement between adjacent strands as herein embodied; and Fig. 5 is aSpecification of Letters Patent.

view similar to Fig. 4 but illustrating a different interlockingengagement between adjacent units.

As disclosed in the accompanying drawings, 1 denotes one of thelongitudinal side bars of a bed frame and 2 and 3 the upper and lowerend or cross bars, respectively, which bars, as herein disclosed, areconveniently and cheaply formed of angle bars and adapted to be suitablyconnected one to the other in a conventional way. The cross bars 2 and 3have their upstanding flanges apertured, as at 4: for the reception ofthe anchoring members 5 and 6 for the fabric proper, the members 5 beingshown as hooks while the members 6 are disclosed as helical springs toafford resiliency and elasticity, as is believed to be obvious to thoseskilled in the art to which my present inventionappertains.

Referring now to the fabric itself, in which the novel features of thepresent invention more particularly reside, this fabric is made up of aseries of parallel longitudinal strands each formed of duplicate orsubstantially duplicate bent Wire units connected end to end, whichunits or links are provided intermediate their length with integrallateral extensions adapted to be interhooked midway of a link or unit inan adjacent strand to connect the latter as well as form spaced fillingelements for the sup port of the superimposed mattress.

Each of the units, as herein disclosed, is formed from a single lengthof wire of suitable gage, according to the load to be sustained, whichwire has its extremities bent inwardly to afford a pair of closelyadjacent parallel longitudinal limbs 7, the overlapping portions of suchinwardly directed extremities being laterally directed and interwoven,as at 8, with the freeends thereof spaced apart and formed into therearwardly directed hooks 9-9 adapted to engage a limb 7 of an adjacentstrand.

The adjacent extremities of the links or units of each strand areadapted to be interlocked and, as herein disclosed, I accomplish thispurpose by having one extremity of the unit or link enlarged, as at 10,to afford an eye while the opposite extremity of such unit or link isbent downwardly and rearwardly to afford a hook member 11 adapted topass through the eye 10 of the adjacent unit or link. This arrangement Iemploy in all the links or units except those units which are adapted tobe engaged with the spring member 6 wherein the coacting eX- tremities,as at 14, are straight. While I have specified these latter units asadapted to be engaged with the anchoring members 6, it is to be observedthat the arrangement of the strands could be reversed and they could becaused to engage with equal facility the members 5, herein disclosed ashooks.

From the foregoing, it will be observed that all of the links aresubstantially of duplicate construction except the units comprising oneof the longitudinal edges of the fabric and wherein such units or linksare not provided with the laterally directed hook members, as isbelieved to be self-evident.

By having the links or units directed as set forth and by having suchlinks or units of one strand engage adjacent strands, as hashereinbefore been described, it will be readily perceived that theparallel limbs 7--7 permit such individual flexibility or elasticitythat when weight is put upon any part of the fabric, it does not in anyway affect the remainder of the fabric. This I have conclusivelydemonstrated in actual practice. I have also found that by having unitsor links constructed as herein set forth and assembled as disclosed, thefabric is substantially noiseless, which is a feature much to bedesired.

As illustrated in Fig. 5, the parts are identical as has been describedrelative to the remaining figures but it is to be observed that ininterlocking the adjacentunits, the hooks 9 are disposed across both ofthe limbs 7 and positioned to either side of the portion 8 whereby itwill be observed that the engagement of the hooks 9 is with the outerlimb 7 in lieu of the inner limb, as disclosed in Fig. 4.

From the foregoing description, it is thought to be obvious that a wirefabric constructed in accordance with an embodiment of my invention isof an extremely simple and comparatively inexpensive nature and isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and by reason of theeffectiveness with which it performs its requisite functions; and itwill also be obvious that my invention is susceptible of some change andmodification without material departure from the principles and spiritthereof, and for this reason I do not wish to be understood as limitingmyself to the precise arrangement and formation of the several partsherein shown in carrying out my invention in practice.

I claim:

A unit for wire fabric, formed from a single strand of material andcomprising a pair of parallel longitudinal limbs, the ends of the unitbeing provided with an eye and a hook respectively for inter-engagementwith similar units, the extremities of the strand being connected atsubstantially the longitudinal center of one of the limbs, suchconnected portion being laterally disposed with the ends thereofseparated and disposed in substantial parallelism and terminating inhooks for engagement with a limb of the parallel adjacent unit.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
